Police jeopardising victim support: union

The privatisation of domestic violence counselling services on the NSW Central Coast will jeopardise victim support, the state's public sector union claims.

The Public Service Association says Police Commissioner Mick Fuller has decided to no longer fund eight counsellor and manager positions that previously served the region out of Wyong and Gosford.

General secretary Stewart Little said on Wednesday the likely privatisation of the services, which have been put out to tender, threatened to destroy a highly-successful partnership with police that moved quickly to support victims.

"The existing service has a unique operational relationship alongside police which focuses on victim safety to reduce risk and victimisation," he said in a statement.

"The counsellors and managers are visible and accessible within a police station and have direct access to the police database, allowing a more thorough risk assessment to take place."

Mr Fuller was "a warrior against domestic violence" before taking the top job, Mr Little added.

The PSA said the region had one of the highest rates of domestic violence in the state.
